re: Oh, Lord: another dead author falls victim to post-mortem publication...
Shel was a busy man, and Runny Babbit was never 'Lost' in a trunk. It was intended to be published but he passed away before it could be done. Why don't you read the book, it's actually quite great!
You can see a Runny Babbit animation as well as a ton of other fun at Shel's official website:
